Chimera 1.5.4 Change Log

It's been a busy couple of weeks since I released Chimera 1.5.0. I delayed this blog post due to the updates I had to make to fix and support additional AMD cards and the Facetime issue. This revision is based on  Chameleon 2.0 Revision 1394 which is the code base for the official release of Chameleon 2.0. Since Chimera 1.4 was released the Chameleon team has included some of what I did in Chimera 1.4 to the trunk. I have also have been supplying some fixes and enhancements to the Chameleon trunk to make future updates of Chimera easier.

The main features in this release are:
  • Support for additional NVIDA and AMD video controllers
  • Inclusion or correction fo some AMD frame buffer names 
  • Facetime fix from olegpronin at insanelymac (of which I have added a new Boot key to bypass this fix if needed (thanks to Lnx2Mac for the idea.))
  • Sandy Bridge HD Graphics support based on the work valv started to support the Mobile HD 3000 controller. I've enhanced it to support mobile and desktop controllers.
Here are the specific edits for this version and as a reminder, all lines starting with a dash will be the name of the affected file starting at the branch root.

 - i386/boot2/boot.h
